Sunghoon HongSunghoon Hong
shong10@syr.edu

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Environmental Monitoring
  • Undergraduate Institute: Trinity College (Hartford CT) (Environ Science)

Graduate Research Topic
I am currently working on two projects. The first one is a chronosequence study on American beech interference with sugar maple regeneration in the White Mountain National Forest where I am also looking at the responses of the two hardwood species to nutrient manipulations, soil chemistry, and stand age. The second one is on foliar chemistry of yellow and white birches and their resorption proficiency and efficiency in nutrient-manipulated plots in the White Mountain National Forest.

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Pennsylvania State University - University Park (Animal Sciences/conc)

Personal Statement
After receiving my agriculture-focused BS I'm excited to be working with data that substantiates how our current society's practices impact the ecosystems we live around. During my undergraduate I participated in a study that examined foliar nitrogen manipulations and the potential for plants to trap emissions (NH4, dust, and particulate matter) from poultry farms. My current focus with nutrient manipulation continues in northern hardwood ecosystems within the White Mountains of New Hampshire; I am analyzing leaf area and foliar nutrient composition along with assisting in projects involving root biomass and production and leaf litter production and chemistry.

Graduate Research Topic
Currently, looking at specific leaf area and foliar chemistry of Pin Cherry and Beech trees in nutrient manipulated plots of N, P, and N+P additions.

Favorite Hobbies
Moth and insect ID, Birding, backpacking, cycling, travel, xc skiing.

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Allegheny College (Environmental Science)

Graduate Research Topic
I am currently studying the effects of nutrient additions (N, P, N+P) on the sap flow in sugar maple trees.

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai
  • Area of Study: FRM Ecology and Ecosystems
  • Undergraduate Institute: SUNY Cobleskill

Personal Statement
My interest span across multiple aspects of forest ecosystems and factors that influence plant productivity.

Graduate Research Topic
I am currently studying the health and productivity of sugar maples based on available soil nutrients in the White Mountains of New Hampshire. My research project is striving to determine what nutrients influence the sugar concentration of maple sap and whether maple sap sweetness can be increased by application of calcium, nitrogen, or phosphorus fertilizer in a forest stand.

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai
  • Area of Study: FRM Ecology and Ecosystems
  • Undergraduate Institute: Minzu University of China (Environmental Science)
  • Previous Graduate Study: SUNY-ESF (Forest and natural r)

Personal Statement
I'm interested in forest-based environmental issues that raised currently. I'm more focused on nutrient cycling and mercury pollution in forests.

Graduate Research Topic
My current project is quantifying total mercury in different tree components at four sites (Huntington Forest, NY; Sleepers River, VT; Hubbard Brook, NH; Bear Brook, ME). I am also analyzing mercury by tree rings and doing data analysis of loon Hg.


Alex YoungAlex Young

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems

Personal Statement
I am fascinated by tree canopy dynamics, specifically microclimate gradients that are associated with height in a tree such as humidity and light availability.

Graduate Research Topic
My current project compares the foliar chemistry of litterfall over time in a young and old stand in Bartlett Experimental Forest, NH.
